Clackamas Fire spokesman Brandon Paxton said the man's friend called 911 after he didn't see him come up for air.

Initial reports that the man jumped off a footbridge into the river were incorrect, according to Sgt. Robert Wurpes with the Clackamas County Sheriff's Office. The man went into the river to swim after his dog, Wurpes said. The dog survived.

Rescuers said he had been underwater for about 30 minutes. He had a pulse while medics took him to a hospital, but he died after they arrived, according to Wurpes.

The victim was identified as 61-year-old Jack William Davies of Sherwood.

"The Sheriff's Office wants to remind everyone to wear life jackets and be aware the water is still cold this time of year," Wurpes said in a news release. "There were no indications that alcohol played a role in this incident. However, the Sheriff's Office advises against mixing alcohol and any water related activities."
